Volume of water used each time hand washing
The prototype for the HappyTap was developed over three rounds of design and testing during the final stage of the UNC WaterSHED Programme. It comes with its own water tank, with no need for running water.
HappyTap has a spout that sprays out with many nozzles for efficient distribution of water over a wide surface, and the friction of rubbing and use of soap under the nozzle spray is good enough to sufficiently clean hands. A tray at the base of the HappyTap catches the used water with no spillage.
The valve of the tap is most likely to wear out with use, and this can be purchased off-the-shelf, and thus relatively cheap and easily replaceable.
